LED waterproof module based on ac single point light

Abstract

The invention discloses an LED waterproof module based on an AC single point lamp. The LED waterproof module is characterized by comprising an alternating current-direct current switching circuit, an ABS inflaming retarding power box (1), a waterproof module body (2) and a PC inflaming retarding lamp shade (6); the alternating current-direct current switching circuit can be directly connected into the 220V electric supply and loaded on the ABS inflaming retarding power box, the ABS inflaming retarding power box (1) is sealed by waterproof heat conduction silica gel, the waterproof module body (2) is connected with the alternating current-direct current switching circuit through a module power line (3), an LED lamp (5) is arranged in the waterproof module body (2), the PC inflaming retarding lamp shade (6) is arranged at the position, corresponding to the LED lamp (5), on the waterproof module body (2), and the PC inflaming retarding lamp shade (6) is once molded by inflaming retarding PVC materials in an injection mode. The LED waterproof module solves the problem that in the prior art, an LED lamp spontaneously combusts and leaks water under severe conditions, and is simple in structure, low in cost, suitable for severe environments with high temperature or excessive rain and long in service life.

Description

technical field [0001] The invention relates to an LED advertising lamp, in particular to an LED waterproof module based on an AC single-point lamp. Background technique [0002] In recent years, the LED advertising sign industry has achieved rapid development. With the rising awareness of global energy conservation and the background of relatively high electricity prices compared with traditional light sources, LED light sources continue to be introduced into commercial, architectural, and advertising signage fields. [0003] At present, the advertising sign industry mainly uses low-voltage modules, and adopts a technical solution of separating low-voltage DC power supply from LED light-emitting components. However, the existing LED light bars still have the following problems: because most of the LED light bars are exposed to the open environment, the working conditions are relatively harsh; especially in summer, although LEDs are energy-saving light sources, their heat g...
